N,N-Dipropyltryptamine (also known as Dipropyltryptamine, DPT, and "The Light") is a synthetic psychedelic substance of the tryptamine class that produces DMT-like visionary psychedelic effects when administered. It is closely related to DMT and is reported to be uniquely similar in its hallucinogenic intensity, albeit with a moderately longer duration and greater unpredictability relative to DMT and other psychedelic tryptamines.

DPT use was first reported in 1973, where it was researched in low doses as an adjunct to therapy for alcoholism.[1] It has also been researched in high doses to induce peak experiences for terminal cancer patients.[2] It has gained some notoriety for its adoption as the primary sacrament for the "Temple of the True Inner Light" in the United States, a Christian off-shoot organization who believe in the ritual use of psychedelics and refer to them as "the true flesh of God."[3]

DPT is commonly consumed via insufflation or orally. Many report the experience of insufflation to be very congestive and painful which, with the rapidness of onset, does not give the user much time to acclimate themselves to its powerful effects. It can also be administered intramuscularly or via vaporization after conversion to the freebase form, and this appears to be the preferred route of administration in research settings. Smoking the freebase is reported to be the preferred route used by the "Temple of True Inner Light".[citation needed]

Very little data exists about the pharmacological properties, metabolism, and toxicity of DPT, and it has relatively little history of human usage. It has long been available on the research chemicals market as a legal, grey-market alternative to DMT, and commercially distributed through online vendors. Many reports also suggest that this substance may be overly difficult to use safely for those who are not already very experienced with hallucinogens. It is highly advised to approach this powerful psychedelic substance with the proper amount of precaution and harm reduction practices when using it.

Chemistry

DPT, or N,N-dipropyltryptamine, is a synthetic indole molecule of the tryptamine class. Tryptamines share a core structure comprised of a bicyclic indole heterocycle attached at R3 to an amino group via an ethyl side chain. DPT contains two propyl groups carbon chains bound to the terminal amine RN of its tryptamine backbone.

The role of these interactions and how they result in the psychedelic experience remains the subject of ongoing scientific investigation.

Subjective effects

Relative to psychedelic tryptamines like DMT, DPT is often reported to be similar in its hallucinogenic intensity, albeit with a moderately longer duration and more challenging effects. DPT experiences are often described as a "bizarre", "unsettling", and "darker" version of DMT experiences. DPT is reported to be more sensual and physical than DMT and other psychedelics with a corresponding amount of adverse physical effects.

At light to moderate doses, users often report a slight sense of anaesthetization and relaxation. As the dose increases, hyper-awareness of one's heart rate and breathing increases and body tremors and loss of muscle control are often reported. The effects of DPT can range from strong euphoria and sensuality to nausea, panic, and intense states dysphoria even within the same experience.

The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWikicontributors. These effects should be taken with a grain of salt and will rarely (if ever) occur all at once, but heavier doses will increase the chances of inducing a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.

Physical effects

Spontaneous bodily sensations - The "body high" of DPT is generally more prominent to that of the better known DMT. There is often the sensation of limbs feeling disconnected from the body, a force pinning the body to the surface on which it lay and body tremors which can often make the user feel aware of but not in control of their body.

Distortions

DPT visual geometry can be described through its variations as intricate in complexity, both abstract and concrete in form, more digital than organic in feel, choppy and only loosely structured in organization, brightly lit, multicolored in scheme, sharp in its edges, fast in speed, simultaneously smooth and glitching in motion, immersive in depth, and consistent in intensity. At higher doses, it is more likely to result in states of level 8A geometry over level 8B.

Hallucinatory states

DPT produces a full range of high level hallucinatory states in a fashion that is more consistent and reproducible than that of any other commonly used psychedelic barring DMT and ibogaine. These effects include:

Machinescapes - These are reported to be more common with DPT than with DMT, which lends to its common description as feeling more "industrial" and futuristic, while DMT visuals can often be described as "ancient" or "earthy" in feel.

Internal hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) - As with DMT, DPT produces high level internal hallucinations at appropriate doses more consistently than most other psychedelics. They are more common within dark environments and can be comprehensively described through their variations as lucid in believability, interactive in style, new experiences in content, non-autonomous in controllability, geometry-based in style and almost exclusively of a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or transcendental narrative in their overall theme, with a tendency towards chaotic disorganization and incoherence.

Multi-sensory effects

Synaesthesia - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring, but seems to only be a prominent part of the experience among those who are already predisposed to synaesthetic states.

Many reports indicate that while DPT possesses the raw hallucinogenic power to induce transpersonal states traditionally associated with "classical psychedelics", it does so in a significantly less consistent fashion due to the utter bizarreness and oft-noted "sinister", chaotic, or "forceful" undertones that can be present throughout the experience. What insights it can lead the user to typically occur during the aftermath and integration phase that follows, which shares some qualities of a typical near-death experience.

The toxicity and long-term health effects of recreational DPT do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because DPT is a research chemical with very little history of human usage.

Anecdotal reports from those who have taken DPT suggests that there negative health effects are not likely to occur from simply trying it by itself at low to moderate doses and using it very sparingly (although nothing can be guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.

Tolerance and addiction potential

DPT is not habit-forming and the desire to use it can actually decrease with use. As with most psychedelics, it is reported to be self-limiting.

Tolerance to the effects of DPT have been shown to not be built in animal models.[5] However, it has been reported to be able to build slightly relative to DMT, although still to an insignificant degree compared to most psychedelics.

Dangerous interactions

Although many psychoactive substances are safe to use on their own, they can quickly become dangerous or even life-threatening when combined with other substances. The following lists some known dangerous combinations, but may not include all of them. A combination that appears to be safe in low doses can still increase the risk of injury or death. Independent research should always be conducted to ensure that a combination of two or more substances is safe to consume.

Legal status

New Zealand: DPT is an analogue of DMT, so is a Class C controlled drug in New Zealand.[8]

Sweden: Following its sale as a designer drug, DPT was made illegal in Sweden on 26 January 2016.[9]

United Kingdom: DPT is a Class A drug in the United Kingdom as a result of the tryptamine catch-all clause.[10]

United States: DPT is unscheduled in the United States. It may be considered an analogue of DET, a Schedule I drug under the Controlled Substances Act. As such, the sale for human consumption or the use for illicit non-medical or industrial intents and purposes could be prosecuted as crimes under the Federal Analogue Act.[citation needed] DPT is a Schedule I controlled substance in the states of Florida, Maine, and Oklahoma making it illegal to buy, sell, or possess.[11][12]
